Summer McIntosh broke her third swimming world record in five days on Wednesday night, clocking 4:23.65 in the women’s 400m individual medley at the Canadian Swimming Trials in Victoria, British Columbia.
The 18-year-old from Toronto lowered her own world record of 4:24.38, set earlier this year, and became the first swimmer to break world records in three different individual events at one long course meet since Michael Phelps at the 2008 Beijing Olympics.
